Check Digit Verification of cas no

The CAS Registry Mumber 75021-56-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,0,2 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 75021-56:
(7*7)+(6*5)+(5*0)+(4*2)+(3*1)+(2*5)+(1*6)=106
106 % 10 = 6
So 75021-56-6 is a valid CAS Registry Number.

Aerobic oxidation of secondary benzylic alcohols and direct oxidative amidation of aryl aldehydes promoted by sodium hydride

Wang, Xinbo,Wang, David Zhigang

supporting information; experimental part, p. 3406 - 3411 (2011/06/17)

We reported herein new reactivities and possible mechanistic implications of a simplest oxidant (NaH/air) uncovered on a broad range of useful transformations, including aerobic alcohol oxidations, allylic alcohol isomerizations and oxidations, cyclopropyl alcohol fragmentations, and direct aryl aldehyde oxidative amidations. These readily implementable transition-metal-free processes feature exceptional material accessibility, operational simplicity, and environmental compatibility, and add new dimensions to its synthetic utilities that are fairly robust yet had not previously been fully realized and systematically explored.
